Calculating the Gibbs Energies of Solvation of 2,2'-Dipyridyl in Nonaqueous Solvents

The Gibbs energies of solvation of 2,2'-dipyridyl (2,2'-Dipy) in methanol (MeOH), acetonitrile (AN), dimethylsulfoxide (DMSO), and N,N-dimethylformamide (DMF) are calculated via quantum chemical modeling. Estimates are made for the contributions from universal and specific types of interaction between the molecules of 2,2'-Dipy and the solvent to the change in the Gibbs energies of solvation of the amine when MeOH is replaced with AN, DMSO, and DMF.
